Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting devices using LEDs are inflexible in shape and size, leading to resource waste when individual LEDs fail, and offer limited lighting patterns, as the entire unit must be replaced.
Innovation Solution
A modular lighting device with a bracket system allowing for various shapes and sizes, where only the faulty unit lighting module can be replaced, and utilizing different lenses and reflectors to create multiple lighting patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire lighting device is replaced when one LED fails, then the lighting function is restored, but resource waste occurs
Solution Approach 1:
The lighting device is divided into multiple independent unit lighting modules, each containing one or more LEDs. When an LED fails, only the specific unit module containing the faulty LED needs to be replaced, rather than the entire lighting device. This segmentation enables selective replacement and reduces resource waste.
2Ease of manufacture
If a fixed shape and size lighting device is used, then manufacturing is simplified, but adaptability to different vehicles is limited
Solution Approach 1:
The lighting device consists of multiple standardized unit lighting modules that can be arranged in different configurations. The bracket structure allows for flexible arrangement of these modules to create various shapes and sizes, enabling adaptation to different vehicle types while maintaining standardized manufacturing of individual modules.
Solution Approach 2:
The standardized unit lighting modules and bracket system serve multiple functions: they can be arranged in various configurations for different vehicle types, allow selective replacement of faulty modules, and support different lighting patterns. This universal design enables one module type to serve multiple purposes across different applications.
3Device complexity
If only one lighting pattern is used, then the lighting structure is simple, but the lighting pattern appears monotonous
Solution Approach 1:
Different unit lighting modules within the same lighting device can have different optical components (lenses, reflectors) to produce different lighting patterns. For example, some modules may have lenses for focused beams while others have reflectors for distributed illumination, allowing multiple lighting patterns to be achieved simultaneously or selectively.
